Java string split with Multiple Characters Delimiter

Question

I have a very complicated output from a function, which i need to use specific word from it.

For example, my output is:

 oracle   11257     1  0 14:01 ?        00:00:00 ora_pmon_sas

I need to get just "sas" word, which is next to "ora_pmon_"

Another example:

oracle   6187     1  0 13:41 ?        00:00:00 ora_pmon_db2

I need to get "db2". So what should be my expression?

JAVA code:

insArray=line.split("what will be between these quotes?");

why are you splitting it if that pattern occurs only once!..does it have multiple such patterns..Please be very specific with your question.. — Anirudha

input.substring(input.lastIndexOf('ora_pmon_') + 1) will do the trick... — Not a bug

well, there may be another word like "asm_pmon_" instead of "ora_pmon_". But the rest of thing is similar. — AloneInTheDark

How about this one?

string = string.replaceAll(".*?ora_pmon_", "");

If you want multiple words in place of ora, then it will be

string = string.replaceAll(".*?(ora|kf|asm)_pmon_", "");

that could be useful but "ora" can be anything like "kf" or "asm". so what's your answer to that case?

Sabuj Hassan Over a year ago

replace ora with (ora|kf|asm) Just add your words there with a pipe in between.

but i only need to find them. if there is no words like "ora_pmon_sas", it should pass it.

You could just do

String sub = s.substring(s.indexOf("ora_pmon_") + 9);

You can simply use String#substring(int i) combined with String#lastIndexOf(char ch)

For example:

String result = input.substring(input.lastIndexOf('_') + 1)

What about ora_pmon_db2_abc ?? I think better sol may be lastIndexOf('ora_pmon_') as per OP question...

You're right, but the OP hasn't noted that there will be such case.
